RATIONALE FOR THE DEVELOPMENT OF "PERFORMANCE COST" NOISE CRITERIA
A review of the literature shows that the more obstrusive the nose and the more demanding the task, the greater is the likelihood of adverse effects of noise on task performance. A study was conducted which varied three levels of task speed or work pace (30, 40, and 50 signals/min) on a paced, serial repetitive task requiring complete and sustained attention under two conditions of aperiodic broadband noise, quiet (50 dB(A) and noise (100 dB(A)). One-hour work periods were broken down for analysis into four 15-minute time blocks. The experimental hypotheses were confirmed. Namely, (1) noise adversely affected performance on a paced, serial repetitive task; (2) the faster the work pace, the poorer was performance; (3) noise more adversely affected performance at fast work paces than at slower work paces; and (4) performance in noise at fast work paces deteriorated disproportionately with time at work. The practical, as well as the theoretical, implications of the research are discussed. A rationale for the development of "performance cost" noise criteria is offered.
